Subgrid-scale modeling of turbulent shear flow with vortons
Subgrid-scale modeling of turbulent shear flow with vortons
We introduce a novel subgrid-scale model for shear flows, exploiting the spatial intermittency and the scale separation between large-scale flows and coherent small-scale structures. The model is highly sparse, focusing exclusively on the most intense structures, which are represented by vortons dynamically regularized quasi-singularities that experience rapid distortion from the …
